I am working on my iMac A1312 (I know this fell under the recall however my machine was not under warranty). Since I work on PC's all of the time, I figured I could tackle my Mac. First off, what I did do was upgrade my graphics card to 1gb and my hard drive to 1.5tb (I know, overkill). So I go and try to reinstall Mountain Lion. After everything is all said and done, I still get the Apple logo with the loading wheel underneath it.



I tried safe boot and as I was holding shift, I got a mix of blinking symbols.. Apple, Folder, and a symbol as if it was a Do Not Smoke sign without the cigarette. Once I let go of the shift button, it went to a solid Apple logo, with the loading wheel underneath it again.



I then tried the verbose start up. I got a bunch of text but then I noticed it said:



disk1s2: I/O error

disk1s2: 0x5 (UNDEFINED)



and then it goes with the undefined for several after, and then just continues to do that.



I went back to disk utilities and verified and repaired the drive, and it was fine.



I am beyond confused on what to do or what I can do now.



Any help would be greatly appreciated!
